Set, at one day shy of 22, to become the youngest post-World War II champion, Pogacar flew on the penultimate stage, an uphill time trial, devouring the 57-second lead that had made Roglic look impregnable before the showdown.

Also amazing: This is Pogacar’s first Tour.

In the end, it wasn’t even close. Pogacar was sensational, not only ripping the iconic race leader’s yellow jersey from Roglic, but winning the time trial, too. Roglic managed no better than fifth, a whopping 1 minute, 56 seconds slower than his countryman.

“Unbelievable, unbelievable,” Pogacar said. “My head will explode.”

Not since British riders Bradley Wiggins and Chris Froome finished 1-2 at the 2012 Tour has one nation taken the top two spots.

But almost everyone — even Pogacar — had been expecting that Roglic would be rolling into Paris with the yellow jersey on his shoulders, on his way to becoming Slovenia’s first ever winner. Roglic had taken the race lead on Stage 9 and held it all the way to Saturday, the worst day to lose it. He now trails Pogacar by 59 seconds.
